Question

This part is the question in my post- question lab:"Recrystallization of commercial aspirin"
!)Determine the percentage of aspirin ( acetylsalicylic acid)recovered from your commercial aspirin tablets crystallization. Youcan assume that 3 aspirin tables should contain 975 mg ofpure aspirin. Where do you think the majority of the aspirin waslost in this process? Give a brief statement that supports yourprediction.
Thank a lot !

Explanation / Answer

Determine the percentage of aspirin ( acetylsalicylic acid)recovered from your commercial aspirin tablets crystallization. Youcan assume that 3 aspirin tables should contain 975 mg ofpure aspirin. Where do you think the majority of the aspirin waslost in this process? Give a brief statement that supports yourprediction. To correctly answer this question, more information isrequired. To determine the percentage of aspirin that wasrecovered, we need to know the mass that was recovered from theexperiment, in other words your experimental yield. Accordingto your question, it states that 3 aspirin tablets should contain975 mg of pure aspirin. Therefore, to determine the percentof aspirin recovered (percent yield), you can use the followingequation. % yield=[(experimental yield)/(theoretical yield)]x 100% Note, that for this question, the experimental and theoreticalyields must have the same units. The theoretical yield should also be adjusted for the number oftablets you used in your experiment if you did not use threetablets. To determine where the majority of the product was lost, theprocedure of the experiment would have to be looked at. Butsteps that frequently cause a loss in product are filtering(suction, gravity) and some types of recrystallization (incompleterecrystallization). Incomplete reaction of starting materialsmay be another cause. The correct answer will depend on theprocedure of your experiment. Hope this helps.
